Anyway my rims are 15" steel merc rims and I was running on 195 65s. I picked up (with the assistance of Mercdoctor) 4 x 195 70s which by now is a fair departure from standard 14" tyres but I got the tyre fitter to check out my previously dented rim. He ran it on his machine and he couldn't find fault with it! Ran true. Said I'd done an excellent job considering it was by eye alone.
So, with all four 70s fitted, I decided to check the speedo accuracy half an hour ago and to my utter amazement it now reads true right up to 70mph for the first time ever. Gears now work better (1st being useful for once) and I also sit a bit higher
